BACTERIOLOGYA Textbook of Microorsanisms

by Fred W. Tanner, Professor of Bacteriology andHead of the Department, University of Illinois; andFred W. Tanner, Jr., Bacteriologist, U. S. Departmentof Agriculture.

The original plan of the book is retained in the

forthcoming fourth edition, with the following new ma-

terial to be found: ultramicroscopic forms of life;variability of microorganisms, including various ex-

planations of modern pleomorphism. Stress is placedequally on pathogenic and non-pathogenic organisms.All chapters have been rewritten to include the latestreliable developments. A large glossary of bacterio-logical terms is included, and 25 new illustrations havebeen added.

Fourth Edition in FebruaryApproximately 627 pages Probable price, $4.50

ERUPTIVE ROCKSby S. James Shand, Professor of Geology, ColumbiaUniversity.

This book deals with the origin, composition and

classification of eruptive rocks, and has a chapter de-

voted exclusively to meteorites. Particular attention

is given to the physical chemistry of rock formations,chemistry and composition of the Earth, and the rela-

tion of eruptive rocks to ore deposits. New chaptersare: Late-magmatic and Post-magmatic Reactions;The Genesis of Pegmatite; Eruptive Rocks and Ore

Deposits. A good balance is preserved between field,laboratory, and geochemical data. Arguments pro

and con are cited to point out the uncertainties in-

herent in nearly all petrological problems.

Third Edition in January 488 pages In press

COMPARATIVEPHYSIOLOGY

by Bradley T. Scheer, Assistant Professor of Bio-

chemistry, University of Southern California.

Material is organized in this book from over 1,000

original papers, to make a study of each of the major

animal phyla. The phylogenetic method is used

throughout; each section gives for a single phylum,

material on nutrition, feeding, digestion, circulation,

respiration, metabolism, excretion, regulation of the

internal environment, and the neuromuscular system.

Important ecological and evolutionary developments

are discussed in summaries of each chapter.

Ready in February Approximately 549 pages

Probable price, $5.50

SYSTEMATICIDENTIFICATION OF

ORGANIC COMPOUNDSby Ralph L. Shriner, Professor of Organic Chemistry,State University of Iowa, and Reynold C. Fuson, Pro-fessor of Organic Chemistry, University of Illinois.

The new third edition gives increased recognition tothe fact that the student's first interest is in theidentification of unknown compounds. However, prac-tice experiments on solubility determinants, elementaryanalyses, and classification tests are still included.The book contains a complete outline of work to bedone. Each chapter corresponds to a step in theidentification process. Many sections have been re-written for greater clarity. Additional classificationreagents are given. Melting and boiling points areincluded in the index, making it much easier to locateany given compound in the tables.

Sharpen Microtome Knives at low cost, with improved resultsThe ALOE Precision Microtome Knife Sharpener

Developed by a manufacturer offine microtome knivesand used commercially for resharpening, this machinehas been thoroughly tested by long use. The apparatusconsists of a special metal honing wheel operated by amotor. The desired bevel is always assured by means ofan adjustable knife support. Knives may be sharpenedwith the Aloe Precision Sharpener many times before re-grinding becomes necessary. Furnished with the sharp- c.ener is a strop consisting ofa linen strop and a leather andrubberized fabric belting, 3 inches wide, mounted withadjustable tautness on a heavy cast metal block, 24 incheslong. A few strokes on the linen- strop provided smoothsoff the burr, leaving a perfect edge.

Even the pinpoint bacterial colonies are easy to count-quickly and accurately-with this new Spencer DarkField Quebec Colony Counter. Employing the principleof the dark field microscope, it has a unique annularreflector which illuminates the specimen symmetricallywith oblique rays of light and leaves the backgroundsubdued. As a result it provides:1. Remarkably uniform illumination-the colonies are

lighted from all sides.

2. Greater brilliance-reflector collects and concen-

trates the light rays.

3. Freedom from glare-only light reflected from thespecimen reaches the eyes of the observer.

4. Enclosed illuminating system-protected from dust,yet permitting easy replacement of the household 40watt lamp.

Equipped with a standard 1.5x

lens, this compact, efficient instru-ment will be welcomed by healthdepartments, hospitals, dairies,breweries, canneries- wherevercolony counts are made. Write dept.A3 for details.
